Burdens Australia

Advanced Products For the Australian Infrastructure

Reduced wasteand inefficiency

Only 25 to 30% of the cost of network infrastructure is from the systems components of cables, pipes, valves, pumps, electronics, telemetry and other active system components.

Burdens Australia targets reduction of the other 70% to 75% associated

with costs of construction Equipment, project and construction

management, logistics, safety, traffic management, storage, heavy

transport and labour.

Waste and inefficiency has plagued Infrastructure Construction around the globe. Burdens Australia’s products are engineered to enable the latest methodologies that improve the speed and efficiency of Network Infrastructure Construction, enhance productivity, improve Build Quality, reduce costs and provide both Operators and Contractors a better return on their investment.

The EZYstack Access Chamber System is a cutting edge design which uses high quality re-constituted and re-cycled composite polymer materials to provide a series of man portable rings which fit together to form a multi-purpose Access Chamber for use in the infrastructure.

Active in Australia & New Zealand and more than 20 countries throughout Europe and the Middle East, EZYstack™ has a customer base that includes water and power utilities, telecommunications operators, rail networks and main roads operators.

Our unrivaled range of products are available directly from Burdens Australia Pty Ltd.

This brochure will introduce you to our range of Access Chambers, Covers and Frames and the accessories to complete your system.

Strong customer service is fundamental to our business and if there are any questions related to any aspect of this brochure, we ask you to get in contact using the details on the back cover.

EZYstack™ is the World leader in preformed access chamber systems.

Surface manhole covers installed in Australia must meet the requirements of the Australian Standard AS3996 (road gully and inspection chamber covers). Products designed to AS3996 are grouped depending on their place of installation.

ChambersAccess Chamber Standards

Unlike manhole covers, there is no Australia-wide Standard for non-concrete preformed access chambers. EZYstack™ has created its own vigorous range of tests to replicate a range of scenarios our chambers may experience when installed. Some of these tests have then been applied on a cyclic basis to further demonstrate our products resilience and strength against site conditions. Wherever possible these tests have been carried out and verified by NATA Accredited test houses.

The EZYstack™ SATURN is mostly utilised for footway installations but due to its excellent vertical load capability it can also be installed in trafficked areas.

EZYstack™ is a range of sectional, modular and structural preformed access chambers. Each chamber is made from 150mm deep stacking sections which interlock to offer flexibility in finished chamber depths. The range has variants for footway and carriage/roadway installations. To help choose the most appropriate chamber for your installation please refer to the strength definition to the left of each description. The strength definitions correspond with the load classes shown on page 5.

The system offers network owners and utility companies alike the ability to construct network access points consistently and quickly to a higher quality than traditional methods. Whilst reducing costs at the time of installation as well as the whole of life of the product.

KEY BENEFITS

• 150mm sections• Sections stack on each other to achieve the

depth required• Structural twin wall design• Independently strong; • Available in 100mm, 150mm, 600mm to

produce a wide range of chamber sizes

EZYstack™ JUPITERMATERIAL Glass Reinforced Polyester Resin

(GRP)

STRENGTH 6

The EZYstack™ JUPITER is ideal for roadway installations as the material used does not suffer from creep, the process where an unsupported or non-compacted sidewall can move over time due to loading from traffic. In addition it provides a much more rigid sidewall in larger chambers and has good thermal stability in extremes of temperature. EZYstack™ JUPITER is also available in a fire retardant material to UL94 5VA.

Offering extreme flexibility, EZYstack™ JUPITER can be fabricated to manufacture any chamber dimension.

• 150mm sections• Sections stack on each other to achieve the

depth required• Structural twin wall design• Independently strong; • Minimum 40 tonne loading• Does not require concrete support• All parts weigh less than 25kg• Huge size range• Keys to surround and surface frame; • Ribs on the outside, grooves on top• Smooth, rib free internal walls• Compatible with existing surface • Covers and accessories• Flat pack component design

KEY BENEFITS

Our unique flat pack designs allow for the best of both worlds, providing the ability to ship chambers with a minimum of pallet space yet still have the strength and quality associated with our EZYstack™ system.

Using a EZYstack™ Access Chamber system can save even more time with our Options and Accessories range, allowing installers to simply place, connect up tubes or ducts, backfill and walk away.

EZYstack™ have therefore developed a range to cater for all network operator requirements.

Focusing on customers needs, we have developed the parts required and offer a pre-fitting service, saving further time on site and providing a consistent build quality.

BASES

•

•

We extrude 100% recycled low density polyethylene chamber bases to suit any chamber size. These are securely fitted to a ring section or bottom of a chamber to provide a clean easy finish to the floor of the chamber. There is no requirement to ‘float’ a floor on site and the floor prevents vegetation and silt from entering. Bases are available with an anti-slip finish, grated drainage holes with silt block, sumps to provide a low point for removal of water and built in cable pulling eyes.

• Chambers deeper than 600mm will usually require steps or ladders for access. We supply high quality drop- in or bolt-on steps to suit customer requirements.

•

•

Conduits, tubes and pipes come in many size and wall configurations and we have developed fittings which provide for the simple transit of these into our chambers. Whilst duct entries can always be made very easily on site, our pre-fit service gives consistent spacing and internal wall finish every time.

The addition of cable glands means they will also stop sand, silt and if required, water ingress at the point of entry.

EZYstack™ CABLE TROUGH

Burdens iDS™ plastic cable trough is ideal for laying in signal and communicationslines underground on railway routes and in power plants and industrial installations. The fact that it can be laid so simply and quickly is particularly useful with short closure times or on difficult ground. Its structural design ensures that it is very stable in spite of its low weight and it provides cables and pipes with effective protection against external influences.

• Horizontal segments - increase strength substantially when installed • Can be laid above ground if earth nails are used • Cover can be installed over two troughs • Cover can be firmly connected even when open • Covers can be opened individually • Cables and pipes that have been laid are easily accessible anywhere and at any time • Cables and pipes effectively protected against external influences • No earthing or insulation necessary • Easy adjustments on-site - ability to mitre 45 and 90 degree angles on site• Cable duct can be laid simply and quickly, cutting down closure times for assembly• Light weight, maintenance-free and 100% recyclable • No jointing components • EZYstack plastic cable trough is reusable
